Definitions

  • the invention relates to photovoltaic plants with longitudinal solar panels and longitudinal reflector elements.
  • Reflectors in photovoltaic systems are used for the better exploitation of irradiated sunlight by means of the backscattering onto the solar cells.
  • the reflectors can for example be arranged in the module below the solar cells, so that the reflected light is reflected once more on the glass plate of the module, but bifacial solar cells with two active surfaces can also be provided.
  • rows of solar cells can also be built up, between which rows of reflectors are then located, wherein solar cells and reflectors are arranged at a corresponding angle to one another so that a substantially stepped construction results, as is known in principle from U.S. Pat. No. 5,511,537 A or WO 2008/016 453 A2.
  • a stackable flat/floor rack for solar panels made up of a wire mesh, which has two angled faces, is known from DE 10 2007 045 554 B3. Solar panels are then applied onto the flat angled face and wind baffle plates are applied onto the more steeply angled face to hold down the racks, wherein the wind baffle plates have reflective surfaces and thus can be used as reflector elements.
  • a device described as a solar roof is known from DE 10 2006 042 808 A1, in which solar modules and bending-resistant reflection faces are connected alternately to a leakproof roof face, for example for roofing a car parking space.
  • the solar roof must be mounted on a suitable substructure in order to be able to withstand snow and wind loads.
  • the reflection faces are connected to the adjacent solar modules in a manner which is not described in any more detail. Water drainage lines can be provided at the lower connections.
  • a photovoltaic arrangement is known from EP 2 075 853 A2, which connects solar modules and reflection faces alternately in such a manner that the reflection faces reflect sun rays, which otherwise fall into the gap between the installations of the solar modules, onto the nearest solar module.
  • the arrangement which is provided for installation on flat substrates, requires a supporting substructure.
  • the reflection faces are connected to the adjacent solar modules in a manner which is not described in any more detail.
  • a supporting structure for solar modules is known from U.S. Pat. No. 4,674,244 A, which has a triangular cross section in order to orientate the solar modules optimally towards the sun.
  • the supporting structure is provided for installation on flat substrates and can carry reflective films on its back, which reflect light rays which fall into the gap between the solar modules onto the nearest solar module.
  • the reflecting faces are adhesively bonded films, a fixing on the solar modules themselves is not provided.
  • EP 1 306 907 A1 describes a photovoltaic plant with longitudinal solar panels is described, which are arranged by means of mounting rails on a flat, essentially horizontally orientated flat substrate at a set angle and in parallel rows with a spacing to one another.
  • the concave faces can have a reflective surface and are therefore also constructed as reflector elements. These are arranged at the back between the rows of the solar panels in such a manner that in each case the upper edges and the lower edges of the solar panels and reflector elements are connected to one another.
  • a solar cell bracket in the form of a basin is known from DE 203 01 389 U1, on which the solar panel is fixed with the aid of two opposite catches.
  • the catches have angled portions for the connection of solar panels and the basin, wherein these do not surround the solar panels.
  • the opposite catches are connected to a web which at the same time is used for supporting the solar panels.
  • a mounting device for longitudinal solar modules is known from JP 2000 064 523 A, which essentially consists of mounting rails arranged on the flat substrate and insert elements fixed thereto made up of two separate metal brackets of different arm length. Each metal bracket has a dual bend at its upper end for the lateral insertion of the solar modules with their two longitudinal peripheral regions.
  • the solar modules are thus also fixed on both sides—as for all solar modules previously—and known from the prior art.
  • bands ibid. reference number 71 in FIG. 7
  • These bands are realised in an elastic manner however and are used exclusively for interposition between the solar panels and the metal brackets of the insertion element. Reflector elements are not provided in both of the previously mentioned arrangements.
  • the present invention provides a photovoltaic plant including a plurality of longitudinal solar panels, a plurality of longitudinal reflector sheets, and a plurality of bending-resistant clamping strips.
  • the plurality of longitudinal solar panels are disposed with mounting rails on a substantially horizontally orientated flat substrate at a predetermined angle and in parallel rows with a predetermined spacing to one another.
  • the plurality of longitudinal reflector sheets are arranged between the rows of the solar panels.
  • the clamping strips are disposed in a spaced vertical arrangement between the mounting rails on a back of the solar panels.
  • Each of the clamping strips are configured to connect an upper edge of a respective one of the solar panels to an upper edge of an adjacent first reflector sheet of the reflector sheets and a lower edge of the respective solar panel to a lower edge of an adjacent second reflector sheet of the reflector sheet.
  • Each of the clamping strips include an upper angled portion.
  • the upper angled portion has an upper front arm and a first fixing device configured to fix the adjacent first reflector sheet.
  • the upper angled portion is configured to receive the respective solar panel at the upper edge thereof.
  • Each of the clamping strips include a lower angled portion.
  • the lower angled portion has a lower front arm and a second fixing device configured to fix the adjacent second reflector sheet.
  • the lower angled portion is configured to receive the respective solar panel at the upper edge thereof.
  • FIG. 1 shows a perspective detail view of the photovoltaic plant according to the invention
  • FIG. 2 shows a side view of the photovoltaic plant according to the invention
  • FIG. 3 shows a first detail from FIG. 2 .
  • FIG. 4 shows a second detail from FIG. 2 .
  • FIG. 5 shows a perspective view of the bending-resistant reflector clamping strip.
  • the invention provides a photovoltaic plant with longitudinal solar panels which are arranged by means of mounting rails on an essentially horizontally orientated flat substrate at a set angle and in parallel rows with a spacing to one another, and with longitudinal reflector elements arranged at the back between the rows of the solar panels with a connection of the upper edge of the reflector element to the upper edge of the solar panel and the lower edge of the reflector element to the lower edge of the solar panel.
  • multi-string solar module in contrast to a “many-string solar module”
  • solar modules or solar panels of this type are designated in the present context with “longitudinal”.
  • Solar modules can have solar cells on panes of glass in constructive frames or also “laminated” solar cells cast in plastic.
  • Solar modules with laminated solar cells can also be designated as “solar panels” and are relatively thin and often bendable.
  • the present invention provides a generic photovoltaic system in which a simple and light mounting of the longitudinal solar panels is possible. Furthermore, a particularly simple, yet in spite of this windproof nature and fixing of the reflector elements should also be implemented. In this case, the reflector elements themselves should be realised as simply as possible, yet also effectively in terms of their reflection action. In both cases, however, the solar panels should in this case be protected effectively from sagging, without an impairment of their effective face.
  • the photovoltaic system according to the invention is characterised on the one hand by an exclusively one-sided mounting of the solar panels in the region of their lower edges on the mounting rails on the flat substrate.
  • the invention is characterised by bending-resistant reflector clamping strips which are used for fixing the reflector elements, principally however also for the stabilisation of the solar panels.
  • the reflector clamping strips are realised in a manner resistant to bending and arranged on the back of the solar panels with spacing to one another between the mounting rails, so that they do not hinder the mounting of the solar panels.
  • the reflector clamping strips have upper and lower dual angled portions, with the front arms of which they in each case surround the solar panels at their two longitudinal edges.
  • the reflector elements themselves are realised as simple thin reflector sheets. Due to the one-sided mounting of the solar panels, these are substantially simpler to mount and also better accessible than known solar panels, which is particularly advantageous for a simple fixing of the reflector elements.
  • the solar panels do not have the stability as in the case of a two-sided fixing because the upper edge of the solar panels is unsupported. Fixing of reflector elements with exclusive supporting on the upper edge of the solar panels would therefore lead to an undesired sagging. Therefore, in the case of the invention, the bending-resistant reflector clamping strips are provided, which surround the solar panels, which can preferably be frameless PV laminates, from the back at the upper and lower edges.
  • the reflector elements are used for the fixing of the reflector elements, which are realised in a particularly simple manner as thin reflector sheet. Spatial constructions are dispensed with.
  • the arrangement and secure connection of the reflector sheets is achieved exclusively by means of their fixing to the upper edge of the one solar panel and to the lower edge of the solar panel located therebehind in the next row.
  • a plurality of bending-resistant reflector clamping strips are, according to the invention, provided over the longitudinal extent of the solar panels.
  • a connection element is provided on the back of the solar panels arranged parallel to their upper and lower edges, which connection element connects all bending-resistant reflector clamping strips on the back of a solar panel to one another.
  • this can be a simple strip which has dual clamping catches in the region of the bending-resistant reflector clamping strips.
  • a simple connection by means of adhesive bonding or other simple connection technologies is likewise possible.
  • the bending-resistant reflector clamping strips are used in the case of the invention particularly for the stabilisation of the solar panels which are fixed on one side.
  • the bending-resistant reflector clamping strips surround the solar panels with the front arms of upper and lower dual angled portions. The solar panels therefore plug into the dual angled portions, as into guiding grooves.
  • the mounting of the bending-resistant reflector clamping strips takes place in a simple manner by means of simple slipping on of the narrow sides of the solar panels or by means of adjustment by means of a length adjustment.
  • the bending-resistant reflector clamping strip has a rib reinforcement at least in the region of the lower angled portion.
  • this can be a single, centrally arranged and radially directed rib, for example.
  • the bending-resistant reflector clamping strips out of a plastic, for example a hard plastic, can simplify the mounting on the solar panel if the bending-resistant reflector clamping strips are pushed laterally onto the solar panels.
  • the bending resistant reflector clamping strips can also have a rigid length setting. In the extended position, they are then pushed over the solar panel and then accommodate the same after the pushing together in the shortened position in their upper and lower angled portions.
  • clamping lips can furthermore be preferably provided within the lower and/or upper dual angled portion of the reflector clamping strips. This embodiment is preferably to be seen in connection with a realisation of the bending-resistant reflector clamping strips out of plastic so that the clamping lips bring the required flexibility.
  • the reflector elements are realised as simple thin reflector sheets in the invention.
  • these can be thin sheets made of a metal or plates or films made from a plastic. All reflector sheets have a reflective surface in their function as reflectors. In this case, the natural reflectivity of the material used or an additional reflective coating can be used.
  • a metal sheet as reflector sheet this can have simple angled portions at the upper and lower edge. With the lower edge, the sheet is pushed simply between the bending-resistant reflector clamping strip and the solar panel and clamped there. With the angled upper edge, the sheet is then simply laid over the upper edge of the solar panel and fixed there, if appropriate.
  • Special means for accommodating the reflector sheets can also be provided at the bending-resistant reflector clamping strip.
  • this can preferably be a first accommodation groove in the end face of the front arm of the lower angled portion for accommodating the lower edge of the reflector sheet.
  • the angled portion of the reflector sheet which is if appropriate folded once more, is simply pushed into this accommodation groove.
  • an inner chamfer of the front arm of the upper angled portion can be provided for accommodating the angled upper edge of the reflector sheet.
  • the reflector sheet is preferably angularly folded twice and simply locks behind the chamfer when pushed over.
  • a second accommodation groove can also be located on the back of the bending-resistant reflector clamping strip in the region of its upper angled portion for accommodating the upper edge of the reflector sheet.
  • the reflector sheet can for example have a thickening at its upper edge, with which it then locks into the accommodation groove.
  • An advantage of the photovoltaic system according to the invention is the one-sided fixing of the solar panels only in the region of their lower edges, as a result of which the solar panels can be mounted better and are accessible.
  • a stabilisation of the solar panels, which are fixed on one side, against sagging is achieved according to the invention by means of the bending-resistant reflector clamping strips.
  • the one-sided holding of the solar panels can take place in insertion elements which are fixed in the mounting rails.
  • a construction of the insertion element as a compact one-piece moulded element with a closed surface can preferably be provided. In this case, the closed surface is only interrupted by an insertion slot which runs over the entire width of the moulded element at the predetermined set angle.

  • the bending-resistant reflector clamping strips 18 are distributed with a spacing 20 evenly over the longitudinal solar panels 02 and arranged between the insertion elements 14 .
  • the bending-resistant reflector clamping strips 18 are connected to one another horizontally using a plurality of parallel connection elements 21 .
